I just reviewed this code path on trunk again, and I couldn't find aproblem. It appears to me that if one future fails, then the exceptionhandling logic will allow the other future to proceed without canceling. Also, I haven't been able to reproduce the infinite loop that you reportedwith the test case that you gave.

However, if you're still seeing a bug on your side, then I recommend filinga new jira issue with a full description. We can continue troubleshootingthere.

Hi Chirs,I write one test case base on HDFS-6231 patch. You are right, no future iscanceled. But I find the while loop in hedgedFetchBlockByteRange methodexecute 30,000 times. Please see hedged-read-test-case.patch in HDFS-6494jira. I think that may be one problem.
